Complex Implant-Prosthetic Rehabilitation Following Sports Trauma with 14 Years of Follow-Up: Case Report

: Tooth loss after traumatic dental injuries (TDI) often requires rehabilitation with a multidisciplinary treatment plan. In growing patients, the therapeutic approach may be different than in adults; the scientific literature offers alternative solutions even if they involve long, complex and uncomfortable treatments. Among the possible therapeutic options, implant-prosthetic treatment through the use of mini-implants is presented in this complex case report with a 14-year follow-up

Sport and Dental Traumatology: Surgical Solutions and Prevention

Trauma is a worldwide cause of millions of deaths and severe injuries every year, all over the world. Despite the limited extension of the oral region compared to the whole body, dental and oral injuries account for a fairly high percentage of all body traumas. Among head and neck traumas, dental and facial injuries are highly correlated to sport activities, and their management can be a real challenge for practitioners of any specialty. In case of trauma directed to periodontal structures, restorative and endodontic solutions may not be sufficient to achieve a definitive and long-lasting treatment. This article aims to illustrate surgical options and appliances to prevent dental injuries that may be available to the clinicians treating dental trauma involving oral soft and hard tissues

The Stille Reaction: Applications in the Synthesis of Organic Dyes for DSSCs

The cross-coupling reaction of organic electrophiles with organostannanes, traditionally known as the Stille reaction, has found renewed interest in the preparation of new organic materials such as conjugated polymers, organic semiconductors and photoactive molecules for use in organic photovoltaics. Moreover, a very recent field in which the Stille reaction has found successful application is that of the design and synthesis of new photosensitizers for dye-sensitized solar cells (DSSCs). DSSCs are considered a promising alternative for energy production from renewable sources. In such devices light harvesting is carried out by a dye which is generally a highly conjugated molecule. Due to the mild operating conditions and the high functional-group compatibility, the Stille reaction proved to be a powerful tool not only for the preparation of photosensitizers, but also to plan their chemical elaboration in order to tune and optimize their photophysical, electrochemical and photovoltaic properties. In this microreview some recent examples of the Stille reaction in the synthesis of organic dyes for DSSC are reported

Synthesis and Characterization of New Organic Dyes Containing the Indigo Core

A new series of symmetrical organic dyes containing an indigo central core decorated with different electron donor groups have been prepared, starting from Tyrian Purple and using the Pd-catalyzed Stille-Migita coupling process. The effect of substituents on the spectroscopic properties of the dyes has been investigated theoretically and experimentally. In general, all dyes presented intense light absorption bands, both in the blue and red regions of the visible spectrum, conferring them a bright green color in solution. Using the same approach, an asymmetrically substituted D–A-π–A green dye, bearing a triarylamine electron donor and the cyanoacrylate acceptor/anchoring group, has been synthesized for the first time and fully characterized, confirming that spectroscopic and electrochemical properties are consistent with a possible application in dye-sensitized solar cells (DSSC)

Nipple trauma in infants? Bednar aphthae.

INTRODUCTION: Bednar aphthae are infected wounds caused by trauma, localized to the hard palate in infants. They do not require specific treatment because they regress spontaneously in a few days. They often remain undiagnosed; other times, because of the pain they caused, they may worsen the nursing.CASE REPORT: We describe the clinical case of a healthy infant of 2 months, fed with formula, who has 2 aphthous lesions in the oral cavity associated with irritability and inconsolable crying during feeding. We excluded the influence of infectious factors or underlying diseases. The hypothesis of a traumatic factor was supported by the anatomical features of aphthae and then confirmed by the gradual resolution of lesions after some advices on breastfeeding.CONCLUSIONS: Our intent is to provide a photographic record of Bednar aphthae, which are quite common but often misdiagnosed also because of lacking of photographic material. Improved knowledge of this condition helps physicians in the differential diagnosis of a traumatic condition that is not as unusual as it seems in newborns

Ectima gangrenoso in corso di sepsi neonatale da Pseudomonas aeruginosa

La sepsi da Pseudomonas aeruginosa (PA) è un evento raro nel neonato a termine, in assenza di fattori predisponenti quali immunodeficienze congenite o acquisite. In età pediatrica può associarsi a discoagulopatia, neutropenia, manifestazioni cutanee (ectima gangrenoso) e otologiche

The use of corticosteroids in the lateral sinus augmentation surgical procedure: A systematic review and meta-analysis

Background The lateral maxillary sinus augmentation (MSA) procedure has good predictability in terms of the success of bone regeneration with a low incidence of postoperative infections, estimated between 2% and 5.6%. Although the use of antibiotics is an established and standardized prophylactic measure for MSA procedures, the addition of corticosteroids still varies among clinician preference and clinical judgment. Purpose The aim of this systematic review was to identify whether the administration of corticosteroids during the MSA surgical procedure affects postoperative symptoms including swelling, pain, and infection rate. Materials and methods A literature search through PubMed, EMBASE, Ovid MEDLINE, and Web of Science indices, according to PICO criteria, was conducted to identify whether MSA peri-operative use of corticosteroids reduces the incidence of complications and patient morbidity. A single arm meta-analysis was performed due to the lack of randomized controlled trials (RCTs) comparing groups treated with or without peri-operative corticosteroids. The intracluster correlation co-efficient (ICC) and design effect were calculated to adjust for the clustering design. Results In the 37 studies included, a total of 1599 patients (378 Cort, 1221 No-Cort) were analyzed. Before and after taking account of clustering, there was statistically significant effect of corticosteroids on swelling, pain, wound dehiscence, trismus, and hematoma. The complication rates postoperatively were comparable between the two study groups, however slight differences existed in the incidence of active suppuration (1.7% [95% CI 0.7–3.9] Cort vs. 3.2% [2.2–4.5] No-Cort), wound dehiscence (3.9% [1.3–11.2] Cort vs. 2.1% [1.0–4.1] No-Cort) and trismus (2.7% [0.8–8.4] Cort vs. 1.4% [0.8–2.5] No-Cort). Conclusions Although the event rate of the 1-to-2-week postoperative complications did not differ between the two groups, the lack of conclusive data and research comparing peri-operative corticosteroid use makes it impossible to draw definitive conclusions and more evidence and studies designed for this specific purpose are needed
